Rated 3.5 out of 5 by 68 reviewers.
Rated 4.0 out of 5.0 by Flushes very well at 1.6 gal. fit Very well under existing counter cause it's a very small unit. Received with a missing important part. My plumber intalled a replacement flush kit just to make it work. After that everything worked great. This is a small bowl. Small seat and low to the floor. Just what I needed. This is a very heavy well constructed toilet. One small rubber white fill tube was missing so the bowl would not fill but my plumber replaced the flush mechanism with one he had on his truck (Thank Goodness). March 27, 2015
Rated 1.0 out of 5.0 by don't do it! flushes poorly, expensive parts, hard to fix this thing is terrible - you always have to flush twice, even just liquids. the handle comes loose, the flapper is a Kohler-only part, 3x normal cost, the flush valve is an odd, twist-in thing that people can't figure out how to install. Mine is leaking and I'm concerned whether I can fix it - I might just have to replace the whole thing. January 8, 2015
Rated 1.0 out of 5.0 by Poor toilet I've been putting up with this toilet for over 3 years. It often clogs. I have to keep a plunger nearby. It has nothing to do with venting either as my vent system exceeds code. It has always had a slow leak with the flapper and it refills every 30 minutes or so. Now the fill valve has failed and it sprays water out the top which ends up on the floor. Unfortunately the fill valve and flapper are propriatary Kohler parts and are not easily replaced. I'm going to have to replace it. It will not be a Kohler toilet. December 16, 2010
Rated 1.0 out of 5.0 by Unique design leads to trouble down the road. Hundreds of complaints related to changing the toilet seat. Seat anchors often get stuck and require $$$ repair kit which may also fail leading to a total toilet replacement that Kohler will not stand behind. Stay away from this one piece toilet or go with the two piece toilet. April 30, 2012
Rated 1.0 out of 5.0 by Terrible Toilet Seat Design DON'T BUY THIS TOILET!! Looks nice, but the design makes it extremely difficult and expensive to replace the toilet seat. This toilet was in the house we just bought. Toilet seat was loose and cracked. Required a $50 part and a $50 toilet seat ordered from Kohler (Home Depot doesn't sell it) just to switch them out. And then the repair part broke during installation so now I'm back with a brand new (but still loose) toilet seat and will have to go through the whole process again. I may just buy a different brand toilet. Google it. You'll find lots of other people have had the exact same problem. July 9, 2011
Rated 5.0 out of 5.0 by small space toilet Have a very small powder room. Researched toilets extensively. There are many out there that are great for a regular sized bathroom. After trying multiple toilets in the space this one fit great. Looks great in the space (small room, small toilet). Wished this was the first one we tried. Would definitely purchase again.

Rated 1.0 out of 5.0 by DONT BUY IT! If you, any member of your household, or any guest you may ever have in your house currently- or plan on going "#2" in the future- do NOT buy this toilet. You will have to plunge it often, snake it, and have plumbers come to your house. The plumber that came to my house said that this toilet & all "boy" toilets are horrible. After a year & four months of fighting with it we are replacing ours. We haven't even used it for "#2s" in over 6 months. HORRIBLE TOILET & NOT WORTH THE MONEY!!!!! February 14, 2011
Rated 1.0 out of 5.0 by not a water saver We have had this toilet installed for six months, it doesn't save on water because most of the time it takes more than a single flush to clean the bowl. I have adjusted the water level inside the holding tank and still this toilet pluggs up. It is quiet, and stylish, but it's a pain in the ..... March 26, 2010
